Alpine apparently spent a long time developing these amps. The amp is tiny compared to other 5 channel amps and puts out an AMAZING clear crisp signal. I have it pushing MBQuarts on the 4 channels and have it pushing a JL 10w6v2 and it is definately suffcient. The ebay seller had it at my doorstep in like 3 days. Perfect condition and brand new!
Generally is a good product and if some one installs the proper equipment this unit works properly.Otherwise it will not give the quality sound it should have.
I love the fact that this one amplifier can run the whole system and fit under my driver's seat. The sound quality is clean and powerful. I have it hooked up to Alpine SPX-13REF speakers, one ten inch Memphis M class subwoofer in a sealed box all hooked up to the Alpine IDA-X100 head unit. Great little system that doesn't take up my whole trunk. I love it!
I purchased an Alpine PDX-5 car amplifier and within a week I received the amp without any problems. I have installed it in my Chevy 2500HD Diesel to 2 pairs of JL Audio ZR separates and a 10 inch JL Audio W3. The sound is great and I'm very impressed with power output from such a small amp. Other amps I've owned have been larger in size and take up to much space. Overall, I'd recommend the amp if you're short on space and want great sound.
Great amp. Easy install. Easily powers a set up separates in the front, a pair of coaxials in the rear and a 10" sub. Gains are set low and still more volume than I can handle.
Class D amp makes a huge difference with size and heat. Other nice things are the hex screw connectors for power, ground and remote. The speaker terminals are screwed into a little plug that also makes it easy.
All around I am quite happy with the amp. The only issue (and it's really a non-issue) is the first few times I really cranked it I smelled a little bit of "burning electronics." Similar to the smell from a new tube TV or something. It's since worn off.
